Researchers demonstrated a prototype "fire alarm wallpaper" that's meant to be flame-resistant while also integrating a nanotechnology-based sensor that triggers a siren and warning lights. Ying-Jie Zhu at the Chinese Academy of Sciences and colleagues published their work in the journal ACS Nano.
"Fire alarm wallpaper detects, resists, and warns of house fires" (Phys.org)
The new wallpaper is based on hydroxyapatite, which is the primary inorganic component of bone and teeth. Although hydroxyapatite is typically brittle and inflexible, in previous work the researchers found that forming ultralong nanowires made of hydroxyapatite gives the material a high flexibility suitable for making wallpaper.
In order to make the nonflammable wallpaper a "smart material" capable of automatically sounding an alarm in response to a fire, the researchers incorporated an ink-based thermosensitive sensor onto the wallpaper.
The thermosensitive sensor is fabricated on the surface of the wallpaper by a simple drop-casting process using an ink containing graphene oxide. The tiny sensor is placed on the backside of the fire- resistant wallpaper so that it is out of sight and protected by the fireproof wallpaper.
The sensor is composed primarily of graphene oxide, which is electrically insulating at room temperature. However, when exposed to heat, the oxygen-containing groups are removed, making the material highly conductive. The sensor is connected to an alarm, so when a fire occurs and the sensor begins to conduct electricity, it causes the alarm to go off.
The SLAC National Accelerator Laboratory in Menlo Park, California recently found a 6th century manuscript by Greek physician Galen, which had been scraped from its pages 500 years later and replaced with religious text. Who needs science when there are religious texts that need copying? Read the rest
When I'm not here pointing out dog videos, I spend the rest of my work day as a technology journalist. I decided that I wanted in on this line of work because I love gadgets. There was always something new coming out that I couldn't afford to buy. Now, as I get to play with new tech on an almost daily basis, I don't feel like I'm missing out on much of anything. My office is full of smartphones, computers, wearables and travel gear. It's loaned to me, I play with it and then, I send it back. It's such a privilege to have access to the sorts of swag that a lot of geeks like me drool over. I never get tired of playing with new products. But having done it for close to a decade has left me a bit jaded: what's new is seldom as spectacular as we want it to be.
Take this year's crop of flagship smartphones, for example. They're a little bit faster, a little bit glossier. Maybe the one you've been looking at has an edge-to-edge display. I get it: bezels on a handset are bullshit, so, you totally want one. I know I do. But I also know, having played with them, that the incremental differences between one year's model and the next is so moot, that they won't make a lick of difference in my day-to-day life. TVs are the same. Most of the folks I know just want the shows and movies that they watch to look their best. Read the rest
Nissan, to show off its autonomous parking tech, outfitted an inn in Hakone, Japan with "self-parking slippers," autonomous floor cushions that tidy themselves, and a TV remote control that straightens itself on the coffee table. While obviously a marketing gimmick, self-knolling anything is quite appealing to me. ProPILOT Park Ryokan (Nissan)
Boing Boing pal Eric Paulos, an engineering professor and artist at UC Berkeley, has a history of high-tech provocations, from his early work with machine performance group Survival Research Laboratories to his controversial art installations such as a vending machine for pathogens. Above is the performance/prank Eric recently staged to open his Critical Making class:

On the first day of class, I wanted to make a point about expectations – about expectations for this course and more importantly about leaving them behind as we engage in the material and topics within Critical Making. Rather than say it or even show a slide, I unexpectedly and dramatically lifted "my" laptop and smashed it across the floor of the classroom.
Next, I setup the room, ensuring that the impact area would be clear and safe and also that I could adequately conceal my real laptop underneath using a haphazardly stacked set of design textbooks as camouflage. You can see my real laptop in the image below, carefully concealed underneath the broken laptop. I was able to easily advance my slides using a handheld remote control. I placed a board across, concealing my real laptop and then placed the staged laptop on top. A few more books covered up the board and a fake cable were attached to the broken laptop giving the illusion that all was normal – as expected.
I rehearsed the staging, where I would stand, what I would say, and how I would grab the laptop. Remember the bottom of the laptop would completely fall apart if lifted improperly.
The "addictiveness of smartphones" is the latest technology moral panic, sending parents off with furrowed brows over whether theire kids' "brains are being rewired" by their phones. Read the rest
NASA uses hundreds of thousands of gallons of water during launches to suppress vibration during liftoff: "a curtain of water around the engines to dampen the loudness of the test and protect the core stage from noise damage". Here's the system being tested!
Water flowed during a test at Launch Complex 39B at NASA’s Kennedy Space Center in Florida. About 450,000 gallons of water flowed at high speed from a holding tank through new and modified piping and valves, the flame trench, flame deflector nozzles and mobile launcher interface risers during a wet flow test at Launch Complex 39B. At peak flow, the water reached about 100 feet in the air above the pad surface. The test was a milestone to confirm and baseline the performance of the Ignition Overpressure/Sound Suppression system. During launch of NASA's Space Launch System rocket and Orion spacecraft, the high-speed water flow will help protect the vehicle from the extreme acoustic and temperature environment during ignition and liftoff.Read the rest

“That's the novel aspect to this study, seeing that chronic, long-term amputees can learn to control a robotic limb,” said Nicho Hatsopoulos, PhD, professor of organismal biology and anatomy at UChicago and senior author of the study. “But what was also interesting was the brain’s plasticity over long-term exposure, and seeing what happened to the connectivity of the network as they learned to control the device.”
Here's the basic setup in a similar lab with non-amputee monkeys. The monkey gets juice or some other treat for successfully completing the tasks.
Here's a detailed lecture on the current work in the field:
